How do you know whether to use masculine or feminine singular adjectives to describe singular nouns?

When describing singular nouns, adjectives can be either masculine or feminine. The gender of the adjective depends on the gender of the noun.For example, take the word "собака" (dog). In Russian, most feminine words end with "-а". This is your signal that the word "собака" is feminine. So if you want to say "big dog", the correct form would be "большая собака".In contrast, look at the word "кот" (cat). It doesn't end with "-а", and is therefore masculine. So if you want to say "big cat", the correct form would be "большой кот".Over time, you will learn to tell by ear whether a noun requires a masculine or a feminine adjective, even without having to first determine the gender of the noun.(Audio and/or video material will accompany this question)
